SOAP.

No Drawing. Application filed July 9,

To all whom it may concern:

Be it known that I, ARTHUR O. ZINK, a citizen of the United States, residing at Rahway, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Soap, of which the following is a specification.

This invention relates to a soap or cleansing composition which is adapted to be formed into a sheet or strips.

Heretofore sheet soap has been made by applying a saponaceous composition to one or both sides of a paper carrier or base, which is not soluble in either hot or cold water and is a source of annoyance as well as likely-to clog up drains.

The present invention aims primarily to provide a soap or cleansing composition which is capable of being formed into a sheet or strip adapted to meet the requirements of the trade and without a, paper carrier or base. It also aims to provide a saponaceous or cleansing composition that will enable the user to effectively remove dirt. Further it aims to provide such a composition that will have a non-deleterious and preferabl emollient action upon the hands. Still fur-. ther it aims to provide a cleansing or saponaceous composition soluble in cold or hot water with the requisite lathering capacity, and preferably alsoa soap that floats.

The invention consists essentially of a composition of soap or other cleansing substance or substances, one or more binders, one or more non-drying agents, which may or may not have supplementary binding properties, and more or less water according to the use contemplated, the composition ormed into a sheet or strip. To a semi-fluid mass of 40 pounds of a co,- coanut oil soap, pounds of acacia, and 30 pounds of glycerin is added twice as much water by weight, and the solution of a syrupy consistency obtained, preferably by heating, is then put in a beater' and whipped to a lather or foam in order to entrap air. This mass or mixture is then spread out on a'flat surface and dried after being leveled or gauged off to about in thickness. The mass is dried either slowly in the air or rapidly by heating. It is desirable to then dust the sheet with a powder, such as soap powder, to prevent its adhesion to rollers in the next succeeding step, which consists in cutting the sheet into strips, and running .it'

through rollers in order to thin to the desired gauge. The dusting with soap powder also facilitates lathering.

The resulting product is a thin sheet of soap preferably about 1/50" thick which is homogeneous, cohesive or tenacious, saponaceous and pliable. By the term pliable is meant flexible or that physical condition which permits the thin sheet of soap to be repeatedly folded. If whipped as mentioned above it will contain minute bubbles of air which accelerate solubility or disintegration of the composition. If the beating or whipping is done properly the soap may be made to float, its bulk varying with the extent or thoroughness of aeration and the amount of Water retained which ordinarily will be around 25%:

There are many and various substances which may be used to make the composition other than the preferred ingredients above quality. Instead of acacia, which functions as a binder, I may employ the following substances soluble in cold water, to wit: mesquite gum, dextrin, galatones, glue (soluble), gelanthum, albumin. Or I may employ glycerinated gelatine as a binder, but this substance is soluble only in warm water. Or I may employ the following binders which are disintegrable, if not soluble, in both hot and cold water, to wit: starchmixture, glycerinated starch, universal gum, althea root, fibrous pulp The starch mixture mentioned inthe last group of alternative binders may be made from 240 pounds of starch or wheat flour, 7 5 pounds of alum, 3% pounds of rosin, and 30 pounds of acacia, upon the starch and renders it adhesive.

gum tragacanth,

the alum in which acts lycerin is the preferred drying resistant,

syrups, such as the trade compound-known which in addition have Borax, sodium silicate or carbonate, abra sive, ,perfumejand coloring agents maybe incorporated as desired. The composition soap above described may be made in strips perforated at intervals for ready detachment to provide an individual wash or it may be made in separate small sheets or pads containing enough soap for a single ablution. Any other convenient way of dispensing the soap may be used however. I

To increase the surface area and accelerate lathering the strip or individual pads may be perforated or corrugated or otherwise superficially roughened.

Advertising .matter may be imprinted upon the sheet and in colors contrasting with the body of the soap to suit the fancy of thepurchaser.

And while I prefer to form the soap into sheets or strips for dispensation, it would be possible to shapethe composition into a variety of other forms such as a rod, bar or tube. But for all practical purposes the strip form is-most suitable.

Acacia and most, if not'all, of the alternative binders previously mentioned are colloidal substances and in the claims the term colloid is employed to comprehend the same.

What I claim is:

1. A toilet soap comprising a thin sheet of pliable, strongly tenacious, homogeneous, saponaceous composition.

2. A toilet soap comprising a thin sheet of pliable, strongly tenacious, homogeneous, saponaceous composition disintegrable in water.

3. A toilet soa comprising a thin sheet of pliable, strong y tenacious, homogeneous, saponaceous composition soluble in water.

A toilet article comprising a thin sheet composed entirely of soap combined with a binder dissoluble in water, and a non-drying agent and capable of being folded repeatedly without rupture.

5. A toilet article comprising a thin, flexible, homogeneous strip composed of soap, acacia and a non-drying agent.

6. A toilet article comprising a thin, flexible, homogeneous strip composed of soap, binder and glycerin.

7. A toilet article comprising a thin, flexible, homogeneous strip composed of soap, acacia and glycerin.

8. A toilet article comprising a thin, flexible, homogeneous strip made from a composition of materials substantially in theproportions of soap forty pounds, binder sixty pounds, and a non-drying agent thirty pounds.

9. The process of making a homogeneous sheet soap consisting in; one, mixing the ingredients; two, thinning the mixture to a syrupy consistency with water; three, aerating the mixture, and four, flowing the aerated mixture on a fiat surface and gauging it off to a substantially uniform thickness and five, drying the sheet thus formed.

10. A thin flexible strongly tenacious sheet of soap comprising a soap and a colloid the product being impregnated with air.

1-1. A thin flexible strongly tenacious sheet of soap comprising a soap, a colloid, and a non-drying agent, the product being impregnated with air.

In testimony whereof, I have signed my name to .this specification.
